I hope someone can help me! (And please forgive the double post, I'm still learning my way around the forums!)

My sister (who lives in another state) and I enjoy playing TTR together on our iPads. But getting a game STARTED is such a struggle!

Here's what I do to initiate a game:

Go into the Station
Click ONLINE GAMES
Click the GAME CENTER tab
Choose her name from the list of my friends
Click INVITE TO PLAY
Click PLAY
In the MULTI-PLAYER GAME WINDOW, I delete ("x" off) the blank players #'s 3 and 4)
Click PLAY NOW
Then it says... Waiting.

The other player gets the banner message that they have been invited to play. But (unless we are missing it) there's nothing they can do to "accept a game."

And we wait. And we wait. We cancel and try it all again.

Eventually we usually get a game going, but we probably make 5-10 unsuccessful attempts (or more!) before that happens.

Are we doing something wrong? Any advice? at the very least, does anyone else encounter this same, very annoying problem?!
